soc/tegra: fuse: Refactor resource mapping

Browse source 
To prepare for adding ACPI support to the tegra-apbmisc driver,
relocate the code responsible for mapping memory resources from
the function ‘tegra_init_apbmisc’ to the function
‘tegra_init_apbmisc_resources.’ This adjustment will allow the
code to be shared between ‘tegra_init_apbmisc’ and the upcoming
‘tegra_acpi_init_apbmisc’ function.
